SLASHER.

CPECIFICATEON foaming art. of Letters Patent No. 350,054, dated September 28, 1886.

Application filed December 19, 1895.

ol- Auburn, county of Androscoggin, and State of Maine, have invented an Inuuovement in Slashers, olwhich the following description, in connection with the accompanying drawings, is a specification, like letters on the d rawings representing like parts.

This invention has for its object to lay in one direction thelibcrs ot' the yarn being sized or acted upon in a slasher or in any usual warp-sizing machine.

In slasher-s as now made brushes are em.- ployed to act upon and lay the fiber uniformly in one direction but the employment of brushes is considered objectionable, because the brushes are kept wet or damp, owing to the application of water thereon in the process of keeping the brushes clean. Pieces of board placed above and below the sheet of warp being sized have been covered with cloth, the cloth coming in contact with both the upper and lower sides of the sheet of yarn; but such wipers are considered objectionable because, upon the stoppage of the machine for any reason, the warp-threads are liable to become stuck fast upon the cloth, and so alsothe cloth becomes coated with size, and the yarn is sometimes broken between the boards covered with cloth, and the broken end is at that point clogged or caught. In accordance with my invention the yarn, as it passes from. the sizing-vat to the usual drying-drum, is led between wiping-surfii-ces, preferably made as rolls covered with cloth, the said rolls being placed alternately above and below the sheet of warp, the latter being drawn between and in contact with the said wiping-surfaces,which effect the laying of the fibers in one and the same direction, the said rolls being by suitable links or connecting devices placed in operative connection with the belt-shipper, so that upon the stoppage of the machine for any cause the wiping'suriaces are removed from contact with the sheet of warp.

My invention consists, essentially, in the combination, with wiping-surfaces aml a beltshipper, of intermediate connecting mechanism. whereby the wiping-surfaces are removed from contact with the sheet of warps when the Serial No. 1811,17 1. (No model.)

licient portion of a warpsizing machine to enable my invention to be understood. Fig. 2

is a top or plan View of Fig. 11, the sheet ol' warp being, however, omitted. Fig. I; is an enlarged sectional detail showing part of one of the stands, the rock-shaft, and one of its carrying-arms, parts of the wiping-surfaces, and the gearing for rotating the same. Fig. 4 is a section of Fig. i in the line :v w,- and Fig. 5 shows a modified form of wiping-surfaces, to be referred to.

The frame-work A, the drying-drums A A", the main shaft a, the belt-pulleys a a? there on, the belt-shipper l'ork b, the rock-shaft I) carrying it, the link. 0*, the shipper lever b, the size-box B, the rolls therein between which the sheet of warp is passed, and the guiderolls 0 c c" are all substantially as in the class of slashers now commonly in use and fully illustrated in No. 98, Vol. 9, ot' the journal, called The Textile Manufacturer, dated February15,'l883,publ ished by Emmott 8s 00., of Manchester, England, among advertisements. On the frame-work I have erected bearings (I, on which I. have placed the rockshaft (1, to which is attached inside the said frame, near eachside thereol', arms 6, the opposite ends of which. are provided with bearings to receive thejournals e 0 (see Fig. 4.) of the wiping-surfacesff, the said wiping-surlaces being shown as rolls, which, in practice, will be covered with cloth or other fibrous mate rial ol' proper nature to act upon the warp 10 and lay the loose fiber thereol. in one direction. At one end thereof the rock-shalt d is extended through a bearingsleeve, j", which is supported in one of the uprights d, the said sleeve having at one enda belt-pulle v, f, and at its opposite end a pinion,f. The journals e 6- of the wiping-surfiices 1 are provided, respectively, with pinions y. The

pinionf" engages and rotates the pinion and 9 with it the wipingsurfaeef The pi nionf,

at its opposite side, engages the intermediate h on the stud h in one ol' the arms 0, and the said intermediate engages a pinion, on and rotates the wipiiig-surfacef. The upper roll,

IOC

1', of the size-box B has upon one end of it a pulley, 2, (see Fig. 2,) which has extended about it a belt, 3, that is extended about the pulley f, The roll 73 is rotated by friction against the roll i below it, the said rotation being effected substantially as in the machine llereinbefore referred to. The speed of rota tion of the pulley f", and the surface speed of the wiping-surfaces f f, being preferably about one-fourth as fast as the speed of the warp through the slasher, or the speed being sufli cient to serve to lay the fibersof the yarn'all in one direction without any disturbance or matting. I prefer that the wiping-surfaces I 5 should be rotated slowly, as described, andin a direction opposite that of the movement of the Warp or other threads being sized; but instead thereof, if desired, I may employ stationary bars, also marked f f 2 and shown in Fig. 5, the said bars, covered with textile material, as stated, being fixed to the arms e on the rock-shaft d. p In accordance with my invention the end of the rock-shaft d opposite that where is lo- 2 5 cated the pulley f is provided with an arm, m, which by the link or eonnecting-rod m, is joined to the shipper-handle I). Vhen the shipper-handle b is in the position shown in Fig. l, the wiping-surfaces/"f stand in the full-line position represented in Fig. 1, and the wiping-surface f bears against the upper side of the sheet of warp, while the upper side of the wiping-surfacef acts against the under side of the sheet of warp w, so that the warp, as it is carried through the machine, is, by the said wiping-surfaces, so rubbed or subjected to friction and rubbing in such direction to lay all the projecting fibers of the individual warp-threads in onedirection. So long as the machine is kept in operation the wiping-surfaces referred to keep the position stated; but as soon as the belt-shipper is moved to carry the belt from thevfast pulley to the loose pulley a, the movement of the shipper-lever I)" through the link m turns the rock-shaft 1]., so that the wiping-surfacesff keep the position shown by dotted line, Fig. 1, in which posi tion both of the wiping-surfaces are removed from contact-with the warp-threads, so that as 50 the machine stands at rest the warp-threads and wiping-surfaces do not become stuck to-' err From the above it will be obvious that the position of the wiping-surfaces with relation to the sheet of warp is absolutely under the control of the belt-shipper, and so long as the belt-shipper is in position to keep the belt on the fast pulley just so long will the wipingsurfaces remain in contact with the upper and under surfaces of the sheet of warp; but as soon as the belt-shipper is moved to shift the belt upon the loose pulley, thus stopping the rotation of the usual warp-receiving beam, not herein shown, but common to the machine referred to, then the wiping-surfaces are automatically and simultaneously removed from contact with the warp.

I do not desire'to limit my invention to the exact construction of the connecting devices between the shipper-lever and the rock-shaft 7o 2, and instead of the particular devices or parts herein shown for such purpose I may employ any other usual or well-known equivalent devices.

I claim 1. The wipingsurfaces and the shaft to support them and the shipper-lever, combined with intermediate connecting mechanism, substantially as described, whereby the position of the wiping-surfaces with relation to the sheet of warp is controlled automatically by the movement of the belt-shipper in one or the other direction, substantially as described.

2. The wiping-surfaces, means, substantially asdescribed, to rotate the said wiping-sun faces'and the shaft to support them and the shipper -lever, combined with intermediate connecting mechanism, substantially as de scribed, wherebythe position of the wipingsurfaces with relation to the sheet of warp is 0 controlled automatically by the movement of the shipper-lever in one or the other direction, substantially as described.

In testimony whereof I have signed my name to this specification. in the presence of two subscribing witnesses.
